MECHANISM FOR OPERATING DISCHARGE-VALVES.

SPECIFICATION forming part of Letters Patent No. 275,344, dated April 10, 1883.

Application filed October 3. 1882.

To all whom it may concern Be it known that I, ALEXANDER G. ALEX- ANDER, of Detroit, in the county of WVayne and State of Michigan, have invented a new and useful Improvement in Mechanism for Operating Discharge-Valves, of which the following is a specification.

My invention consists in so combining the outlet-valve of a water closet or tank with a bucket adapted to hold water that when the valve is opened the bucket will hold said valve open until the water in said bucket escapes through a small orifice therein, and will then automatically close said valve.

Figure 1 is a plan view. Fig. 2 is a side view, partly in section. Fig. 3 is a vertical section. Fig. 4 is a perspective of the tipping bucket, and Fig. 5 is a side view of the bucket with its side wall partly broken away.

A represents the bowl of a water-closet.

B represents a trunk or chamber connected with bowl A by a pipe, I, and adapted at its bottom to connect with an ordinary soil-pipe. B is divided into two chambers by a wall or partition, as shown in Fig. 1. In the smaller of these chambers (marked H) is a ball-valve, F G, which controls the admission of water to bowl A through pipe N, there being a free water communication between pipe I and chamberHthrough pipe S, Fig.2. Thepipe S should be of a diameter considerably larger than the pipe N, so that the water can readily flow from the bowl A to chamber H. As the water in the bowl and chamber will stand at the same level, the chamber should be so arranged that thewater-line at which'the float or ball-valveFG will close will be the line at which it is desired to hold the water in bowl A. Water will enter the bowl A from service-pipe through pipe N, and from thence it will pass through pipe S into chamber B. When the water in the chamber H rises so as to reach the float G it will raise the same, closing the valve F and shutting olf the supply through pipe N. The end of pipe I which opens into chamber B is beveled to form a valve-seat on the inner wall of said chamber.

0 represents a bucket of peculiar shape, as shown in Figs. 4 and 5, hung on a shaft, 0,

5'0 journaled in the walls of chamber B. The

point of attachment of said bucket O to shaft 7 O is well to one side of the center of gravity (No model.)

of said bucket, arm B being secured to said bucket for that purpose. Bucket O is made in two parts, a and V, separated by a wall, 0, in which is a hole, it. Part V iscovered at the top,and has in its rear edge a hole, T. To thebottom of part u is secured a valve, J, adapted to fit the valve-seat on the end of pipe I. Through valve J is cut a hole, j, so that the water in bowl A and pipe I passes freely into bucket O, and stands at the same height in said bowl and bucket, and-said bucket serves as an overflow in case valve F should fail to work.

K L represent inclined planes or wedges, secured respectively to the outer wall of bucket C and the inner wall of chamber B, and coact to force valve J against its seat D.

P represents a pull-rod attached to the end of a crank-arimp, fastened on the end of shaft 0.

The operation of my invention is as follows Bucket 0 being in the position shown in Figs. 1, 2, 3, water will pass into. bowl A through pipe N, and will rise in said bowl and bucket until shut off by valve F. On raising pull 1 P aft 0 will be rocked and bucket C will .ipped toward -the left, Fig. 1, until it strikes the rear wall of chamber B, thus opening valve J and allowing the contents of bowl A to discharge through pipe I and chamber B. The water in partv of bucket C escapes through holesj and t, and the weight of water in part V of said bucket holds said bucket tipped until the water therein has escaped through hole T, thus holding valve J open. It is evident that the time during which said valve will be held open may be regulated by increasing or diminishing the size of hole T. As soon as the water has escaped from bucket G the weight of said bucket causes it to fall back to its original position, wedge K strikes against wedge L, and valve J is forced to its of the closet, and adapt-ed, when tipped, to hold said discharge-valve open until the water contained in said tipping bucket escapes through a small orifice therein, and then automatically close said valve, substantially as set forth.

2. In combination with the discharge-valve.

of a water closet or tank, a tipping bucket arranged to be filled with water from the bowl of the water-closet, hung on a pivot at one side of its center of gravity, and so proportioned that when partially filled with water and tipped the Weight of the water therein contained will transfer the center of gravity to the other side of said pivot until said water has escaped, substantially as set forth.

3. In combination with the discharge-valve of a water closet or tank, the bucket O, having parts 0) V and hole T, hung on shaft 0, connected with the discharge-valve, and provided with a suitable mechanism whereby the same may be tipped, substantially as herein set forth.

4. The combination of the tank B, having the'inclined plane or wedge L, and the bucket 0, provided with the inclined plane or wedge K, the faces of said inclined planes or wedges acting together to. press the valve J, carried by the bucket O, to its seat, substantially as and for the purposes described.
